DOOR-KNOB.

SPECIFICATION forming part of Letters Patent No. 280,728, dated July 3, 1883,

- Application filed February 27, 1883. (No model.)

' Wayne and State of Michigan, have invented a new and useful Knob for Locks of Doors and Door-Bells, of which the following is a specification, reference being had to accompanying drawings, forming part thereof.

This invention relates to certain improve. ments in knobs for doors, bells, and other like purposes; and it has for its objects to so construct such knobs that a disk or plate bearing upon its face any suitable figure or device Such as the photograph or name of the owner or occupant of a house, or the number of the l1ousemay be secured. to the knob and exposed to view, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a front elevation of my improved knob; Fig. 2, a perspective view,

showing the rear of the front portion of the knob; Fig. 3, a side elevation of the rear portion of the knob, and Fig. 4 a detached View of the disk bearing the device or inscription.

My improved knob is constructed in two parts. (Indicated, respectively, bythe letters A and B.) The front or outer portion, A, is of annular shape, and at its rear is rabbeted, as indicated by the letter O, to form a seat forthe plate D, which bears the device or inscription upon its face. The rabbeted portion of the said outer part of the knob is provided at diametrically-opposite points with abutments E, which are provided with screw-threaded apertures F, into which the screws pass which hold the parts together.

The letter G indicates lugs secured in the rabbeted portion, against which the back plate rests when in place. Two of these lugs are placed closely together, and between them the lug M on the back plate is adapted to sit to lock the parts. The back plate is provided with the usual boss, in which is formed the ordinary rectangular seat, in order that it may be set over and secured to theknob-shaft, and the said plate is' also provided with apertures H for the screws which secure the parts together.

The letter I indicates the plate bearing the device or inscription, which plate may be of metal or any other suitable material. It is set in the rabbeted portion of the front part of the knob, with the device or inscription to the front. A backing consisting of a disk of .felt may be placed upon it, if desired, after which the back plate is placed in position and secured by means of screws. plate of glass, mica, or other material may be placed in front of the plate bearing the device or inscription, if desired; but this is not necessary.

The knob is applied, in the same manner as ordinary knobs, by slipping it upon the knob shank and fastening with a screw.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I The combination, in a knob, of the annular rabbeted front portion having perforated threaded abutments for the binding-screws, and supporting-lugs in the rabbet, the plate bearing a device or inscription on its face, and

the back portion having a lug adapted to fit between the lugs on the front portion, the

whole secured by. means of screws, substantially as specified.
